CAN-SOLDERING MACHINE.

T LPECIFICATION forming part of Letters Patent No. 336,659, datedFebruary 23, 18E6.

Application filed December 8, [885. Serial No. 184,643. (No model.)

To all whom it may concern.-

Be it knownthat I, DAVID M. MONROE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Can- Soldering Machines, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to improvements in can-soldering machines, in whichthe side or body seams of sheet-metal cans are soldered, asillustratedin the accompanying drawings, in which- Figure 1 is a top view. Fig. 2is a side view of the machine; Fig. 3, a rear end view of the gagingdevice; Fig. 4, a side view of the gaging device; Fig. 5, a verticalsection of the gaging device; Fig. 6, a front end view of the gagingdevice; Fig. 7, a horizontal sectional view of the gaging device; Fig.8, a top view of the gaging device. Fig. 9 is a sectional view of therail, showing the weight-releasing mechanism and an end View of thegaging de vice. Fig. 10 is a side view of the weight mechanism. Fig. 11is a front view of the soldering-rollers. Fig. 12 is a sectional view ofthe solder-receptacle. Fig. 13 is a sectional "iew of theflux-receptacle.

Similar letters refer to similar parts throughout the several views.

This machine is construct-ed to have a continuous motion by which thecan-gaging device is continually moving at the time the difi'erentoperations are being performed; and it consists of a frame, A. supportedon suitable legs, 13, provided with two wheels, G-one being arranged ateach end of the machine around which travels a chain consisting of asuitable number of links, D, secured together in any suitable manner, inthis instance being pivoted. On this chain are arranged the gagingdevices E, which consist of a split cylinder, 6, and the standards 6',provided with circular holes in which the said cylinder is placed, andwhich is expanded by the sliding rod F, supported in the bearing f, andsecured to the cylinder by means of the pivoted bars f, which arepivoted to both the rod and cylinder, thereby forming a togglejoint,which, when the rod is moved to the left, expands the cylinders, andwhen moved in the opposite direction contracts the same, which per mitsthe rolled sheet-metal blank to be placed in position. This is thengaged by expanding the cylinder and forcing it against the standards e,and is there held in the gaged position until soldered. The upper partof the stand ards c are cut away to form the opening 9, at which pointthe seam ofthe can-body is placed, by which the soldering operation canbe performed.

As it is important in machines of this class to only apply the solder,flux, &c., when a can-body is on the device on account of keeping thesame free thereof. I arrange a device by which this is accomplished. abar, G, swung to the standard 6 by means of suitable links,which permitit to be swung in and out, and it is provided with an inclineprojection, 9, part of which extends into cylinders. XVhen there is nocan-body on the same, but when the said body is slipped on the cylinder,its ends come in contact with the incline,which pushes and holds the barG out, and which is then in a position to operate the solder and fluxapplying devices; but if the cylinder were minus a body, the said barwould not project far enough out to operate the said devices.

The device that operates the expanding mechanism of the gages E consistsof a weight, L. which is secured to a pivoted arm, Z, attached to thefinger P, which holds the weight up by engaging with the spring -arm 1which is pushed to one side by the inclined surfaces on both finger andarm coming in contact with each other when the weight is raised. Thefinger thus holds the weight up until released by the bar G coming incontact with the arm Z, which releases the weight, and it, falling,strikes the end of the rod F and forces it inward, which expands thecylinder and the body placed thereon against the standards a, and holdsthe same in that position until released, which is accomplished by likeweight mechanism 1?, placed on the other side of the frame A, butarranged to act in an opposite direction to the one L, the weight beingelevated by the gages E coming in contact therewith as they pass along,which automatically accomplishes the same.

The fluxing device H is seen red to the frame It consists of A, andprovided with a series of holes in its bottom, over which vibrate thearms h, secured to the rod h, which is attached to the arm it, thatextends downward and which comes in contact with the bar G as the gagepasses under, and thereby operates it, which passes the arms it over theholes and ejects a sufficient quantity of flux on the can-seamimmediately below, the flux being pulverized rosin or a similarsubstance.

The soldering-receptacle I is secured to the frameA and provided with anejection-orifice, '5, in which is placed a cut-off stem, '5 attached 7to the lever i that is pivoted to the receptacle and projects downwardand comes in contact with the bar G as it passes thereunder, therebylifting the stem 2' and permitting a fine stream of molten solder to bedeposited on the canbody as it passes under, which will either form in awire or in small pieces thereon, which is sweated into the seam by theirons farther on, the solder being kept in a molten condition by burnerssuitably arranged, playing continually their flame thereon.

The soldering apparatus consists of a bar, B, centrally pivoted to anarm, which is attached to the frame A, and provided with a series ofrollers, 1*, which are arranged to rotate independently, and which areheated to the desired temperature by means'of hydrocarbonbnrnersarranged to deliver their flame thereagainst, by which the said rollersare always in contact with the flame, and thereby snficiently heated tofuse and sweat the solder in the seam of the can-body as it passes underthem.

The machine'is driven from the shaft 7", which is provided with thegear-wheel r secured to the shaft by means of a groove and feather, sothat it can be shifted in or out of gear by means of the handle 9", withthe wheel 1' on a vertical shaft which extends up through a bearing inthe leg of the machine and communicates with the wheel 0, therebyturning the same and also the chain therewith.

In operating the machine the attendant in this instance stands at theleft-hand end of the machine and places the rolled unseamed bodyblank onthe cylinder of the gaging device by placing it in the space between thecylindere and the surface forming the opening in the standard '6 fromthe rear end, from which it passes to the weight L, which is dropped andthereby expands the cylinder, which then relifts the weight as it passeson, ready for the follower gaging device. The next operation is to applythe flux by the bar G coming in contact with the arm h, which operatesthe same and ejects the flux on the can-body, after which it passes tothe solder-applying device, which is operated likewise and the solderdeposited, whence it passes to the heated irons, which fuse and completethe soldering. The body is then cooled by natural or artificial means asit passes from the irons to the releasing-weight, which falls and movesthe rod F to contract the cylinder, which then releases the solderedcan-body, and which is removed therefrom by the arm T coming in contactwith the edge of the body and pushes it out of the gage into a basketplaced to receive the same.

Instead of using the means to apply the solder, flux, &c., they all orin part may be dispensed with and these functions performed by hand.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- 1. In a can-soldering machine, thecombination of the frame A,the chain consisting of links D, means toimpart thereto a continuous motion, and the gaging device E, placed onthe said chain.

2. In a can-soldering machine, the combination of the endless chain, thegaging device E, mounted on the chain, the wheels 0 0, means to impartto one of the wheels motion, and the soldering-irons arranged to solderthe can body seam as the said body is passing thereby.

3. The combination of the endless chain, the gaging devices E, mountedon the chain, means to impart to the chain motion, a solderingirondevice arranged to solder the seam as the body ispassing by, and thesolder-applying device I.

4. The combination of the chain, the gages E,mounted on the chain, meansto impart motion to the chain, the soldering-irons arranged to solderthe seam as it passes by, the solder-. applying device I, and theflux-applying de vice H.

5. The combination of the chain, the gages E, mounted on the chain, thesoldering-irons arranged to solder the seam as it passes by the solderapplying device I, and means to operate the gaging devices by which thecanbodies are gaged or released.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID M. MONROE.
